Step 1
Find the area of one equilateral triangle
Applying the law of sines

in this problem
a=b=7 cm
C=60 degrees
so

cm²
Step 2
To calculate the area of the hexagon multiply the area of one equilateral triangle by 
cm²
therefore
the answer is the option
73.5 sqrt 3cm²
I believe you would need to divide 123.75 by 7.50.
The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours
Answer:
b
Step-by-step explanation:
Step-by-step explanation:
sin theta = 12/13
cos theta = 5/13
tan theta = 12/5
cosec theta = 13/12
sec theta = 13/5
cot theta = 5/12
Answer:
B.) P(A/B) = P(A)
Step-by-step explanation:
If two events, A and B are independent:
We have that:

Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
Since they are independent:

Then

So
, or either:
, and thus, the correct answer is given by option B.
